To all whom it may concern: I

Be it known that I, SINCLAIR W. CHILES, Of South Bethlehem, county of N orthampton, and State of Pennsylvania, have inventedan Improvement in Dirt-Elevating Pumps of which the following is a-specification.

My invention has reference to dirt-elevating pumps; and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide an efficient apparatus which may speedily and inexpensively elevate dirt or other material from cassions, wells, and other deep places from which such material is to be excavated or moved.

My invention employs compressed air, steam, or liquid under high pressure as the motive force for moving the dirt through the pipes, and my improvements are now more practically directed to the means by which the dirt may be fed tothe pipe intermediate of the applications of the compressed air, whereby the latter may be brought into play upon each fresh charge of material to put it into circulation in its passage upward.

My invention consists of a case having a chargi H -hopper.or entrance, a discharge-outlet for t e discharge of the material, and an inlet for the compressed air, combined with a movable hollow valve portion inclosed within thecase and having apertures corresponding to the apertures in the case, but so disposed that when the hopper is open to the interior the air-inlet and discharge openings are closed, and vice versa, so that the interior may be first charged and subjected to high pressure to discharge the contents.

My invention also comprehends means within the hollow valve portion for breaking down or disintegrating any material which might pack and clog the machine, said means being operative during the time of discharging the material from the apparatus.

My invention also embodies many details of construction, which, together with the featuresabove specified, will be better-understood by reference to the drawings, in which Figure 1 is a transverse sectional elevation of my improved dirt-elevating pump. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is an elevation of the same with a portion of the hopper broken away,

and Fig. 4 is a cross-section through one of the bearings of the case and valve part.

Ais the case, and is shown in spherical form, though this is not at all essential. The case is provided with an opening D at the top, which is fitted with a conical hopper B, through which the dirt is thrown into the case. This hopper may be provided with a coarse grating or screen B to prevent large stones entering the case. The case is also provided at one side near its bottom with an air-inlet F and on the opposite side about its middle with a discharge-opening E, prefer ably directed obliquely upward.

The caseAis formed of two partsnamely,, A and A which are fitted together by a tongue-and-groove joint, as shown at C, which while maintaining a comparatively tight joint allows for adjustmentto compensate for wear between the movable valve portion J and the case. As shown, the union of the two parts A A is in a plane passing through the axis of the pump and slightly inclined, so as to include the discharge-opening E in the upper section A. The .two parts A A are flanged, and bolts 0, passing through the flanges, clamp the two parts together. Set-screws G, Fig. 3, are employed to adjust the two parts and limit the extent to which they are drawn together. As the presdent that four of these set-screws G are suificient, whereas many bolts 0 are necessary to resist the internal pressure when moving the materials. 1

J is the movable valve portion and is shown as a hollow sphere having the apertures D," E, and F, corresponding to theapertures D, E, and F in the case, but with the difference that when the apertures E F are in alinement with the apertures E F to form a through passageway the aperture D is out of alinement with the aperture D, and vice versa. To reduce the friction and insure practically tight joints, I prefer to provide 100 the inner part of the case adjacent to the apertures D, E, and F, respectively, with wearing-faces d, e, and f, against which the valve part J directly works.

I prefer to thicken the interior portion of 105 the valve J between the apertures E and F, as at R, so as to more properly guide the dirt through the discharge-openi ng E by the blast of air from the inlet F. This valve J is adapt- 5 sure is to force the parts A A apart, it is vevied to oscillate in bearings I, in which the no trunnions J are journaled. These bearings are split and the two halves adjusted toward each other by set-screws '5. These bearings I are carried in side extensions H of the case A, and they, like the arts A A are provided with joints C o' tongue-and-grooved character, as shown in Fig. 4. The trunnion J on one side of the valve extends outward, as at J J ournaled in the trunnions is a transverse shaft K, having within the valve J a series of arms L, adapted to break or disintegrate any dirt or packed material which may be in the valve, so as to insure its passage through the discharge-opening E. The end of this shaft K extends beyond the trunnion part J 2 and is fitted with a ratchet-wheel N. J ournaled upon the shaft K between the ratchet-wheel and trunnion is a lever M, which carries a pawl a, engaging with the ratchet-wheel, and also a latch O,whichmay be made to engage with a notch in the part J 2 of the trunnion'for rocking the valve ortion J by the lever M. If there is any 0 ogging of the interior, the latch O is raised and the lever M rocked for rotating shaft K and its arms L.

The operation of the apparatus will now be understood. The valve J is turned so as to bring the opening D in line with the hop eropening D and close the openings E an F. The dirt is then shoveled into the hopper B and passes into the valve-body J. The valve is then turned a quarter of a revolution to the position shown in Fig. 2, and this permits the air under about sixty pounds per square inch to rush through the opening F and drive the dirt upward through the outlet E and the piping connected therewith. Any dirt which may pass between the valve part J and the casing A will act as a packing to prevent escape of air through the joint C.

.The air may be supplemented with water, if

so desired, so as to keep the dirt more in a pasty or fiuid condition. After the discharge of the contents of the valve portion J it is rocked back to the original position and again recharged, the air-pressure being shut off at this time and the contents on the discharge side of the opening E being prevented from descending backward into the valve. The action is intermittent, and the materials are propelled through the discharge-pipe in an interrupted advance.

It is evident that the spherical form of my apparatus is strong and condensed; but it is not at all essential, as any other shape may be em loyed so long as the valve may rotate or roc within its case and control the several ports. Therefore, while I prefer the construc tion shown as being excellently adapted for the purposes of my invention I do not restrict myself to the details, as these may be modified or varied Without departing from the spirit of the invention.

I claim as new, and desire to secure by Letters Patent, is-
